Mint.com sent its members scores of empty emails, and the rash of odd transmissions has its members wondering what is going on at the online personal finance management service owned by Intuit.

Mint acknowledges that it sent the emails from stage-mini@mint.com late last Tuesday, and blames the errant missives on a “misconfiguration of our email provider” as a result of “testing something on our staging server.”

The explanation is not ringing true with Mint members, some of whom received more than a dozen empty emails.
